Seven-time Wimbledon champion Roger Federer has refuted claims that the showcase ATP tour final should move from London.

The former world number one made his claims after Novak Djokovic and Rafael Nadal suggested a change which would see the season climax move from its current home of the O2 Arena, bbc.co.uk reports.

Nadal said he wanted to see a shift away from an indoor event, whilst Djokovic claimed that an annual change of country would be fairer on fans. Djokovic may have more sway in the debate this morning, though, after he won last night’s (Tuesday) final, beating Federer 4-6, 7-6, 2-6.

Federer, who is the third most successful men’s singles player of all time and has won more grand slams than any other player, refuted their claims, however, saying that the current format worked well and therefore did not require a change.

His claims are expected to be welcomed by tennis supporters and businesses in London alike, with the event welcoming its one millionth fan through the turnstiles during the 2012 event. It also welcomes audiences from around the world and could even be responsible for driving up business travel in the capital, as firms from around the world look to organise meetings around the event.

Making his claim, Federer told espn.co.uk: “I truly believe the World Tour Finals should stay indoors, and I think indoors deserves a great event.

“What’s good about playing indoors is that you know what you’re getting in to. Matches are going to be played and not delayed. Indoor clay is not something we should look at. That’s why probably it has to stay indoor hard in my personal opinion.”
